Abstract: PRECODING FOR ODD ERROR MULTIPLICATION IN DIGITAL SYSTEMS                    WITH DIFFERENTIAL CODING by AKE SEWERINSON     ABSTRACT OF DISCLOSURE     Differential encoding is commonly used in data transmission systems because it allows correct recovery of the data even though the polarity may have changed during transmission.  However, single errors which are introduced result in double errors, i.e., error of an even number following the differential decoding process.  Because many error detection schemes rely upon parity checks, which look for an odd number to determine if an error has occurred, the conversion of the single error to a double error means that single errors normally would not be detected.  A precoder is used to introduce correlation by modulo two addition of the precoded present digit with a selected combination of past digits.  The differential decoder will still provide double errors but a subsequent decoder, which reverses the precoding process, at least partially changes double errors into errors of an odd number.

Abstract: Elevator Car Load and Position Dynamic Gain Compensation Abstract A polyphase induction motor propels an elevator car.  The motor is powered by a multiphase inverter which receives power from a battery.  The inverter is controlled in such a way as to control the fre-quency and amplitude of the power supplied to the motor in order to control the motor's speed, accel-eration, and slip.  That inverter control is accom-plished by sensing the motor's speed and in response providing predetermined slip and torque signals. The slip can be controlled over a range which can provide negative slip, by which power is regenerated into the battery, which is thereby charged, and posi-tive slip for motoring torque.  A charger also charges the battery.  The motor and its controls are thereby ostensibly isolated from the power system that supplies power to the charger, the battery handling the peak power requirements.  Loop gain is adjustable in relation to cab loading, and offsets are applied within the loop to adjust the production of the slip and torque signal to reflect cab load and to modify car motion as the car is slowed when approaching the floor for a stop.

Abstract: GRAFT COPOLYMERS AND PROCESS FOR THEIR PREPARATION      ABSTRACT OF THE DISCLOSURE   Under particular conditions, a cationic ring-opening polymerization of an oxirane monomer selected from the group consisting of an acyclic glycidyl ether, a cyclic glycidyl ether, and haloalkyl epoxide, in the presence of a hydroxyl-containing backbone of a polymer ("HCB") and a particular catalyst, produces a polymerization having 'living polymerization' characteristics, provided the OH groups are aliphatic OH groups and not aromatic OH groups.  The result is a graft copolymer the molecular weight (mol wt) of which is directly proportional to the conversion of the monomer.         The HCB, which may have from 1 to about 400 pendant OH groups, and more preferably at least 7 pendant OH groups, provides grafting sites for the grafting segments.  where a grafted segment contains halogen, the segment may be aminated.  If the HCB is hydrophobic, the aminated block copolymer is amphiphilic.

Abstract: HYDRAULIC BRAKE ACTUATOR Abstract of the Disclosure A  hydraulic  brake  actuator  for  a  wedge  type  brake induces a tubular structure extending from the brake and housing an extended end of a stem of the wedge of the brake therein.   A  primary  cylinder  is  mounted  on  the  tubular structure and includes a primary piston mounted for sealed movement therein.  The piston has a rod extending from one side thereof into the tubular structure to be operably connected to the extended end of the stem.  A spring acts on a second side of the piston and is capable of moving the piston  toward  a  first  position  within  the  cylinder  for actuation of the brake.  Hydraulic fluid can be selectively introduced to the primary cylinder at the first side of the piston  to cause  movement  thereof  in  opposition  to  the spring  to  a  second  position  to  prevent actuation of the brake by the spring.  An annular space between an interior surface of the tubular structure and an exterior surface of the rod is sealed to prevent the hydraulic fluid from escaping  from  the  cylinder.   The  sealing  includes  a floating seal carrier surrounding the rod and supporting a seal which extends  inwardly  to make sealing contact with the exterior of the rod and a mechanical face seal at the end of the floating seal carrier to prevent the escape of hydraulic   fluid   behind   the   floating   seal   carrier.

Abstract: ABSTRACT OF THE DISCLOSURE           A paper sizing agent is disclosed.  The sizing agent is obtained by alkali saponification of a reaction product which is obtained by reacting a propylene oligomer with maleic anhydride under heating in the absence of a catalyst.  The propylene oligomer contains substantially no oligomers having 10 or less carbon atoms.  Further, the content of oligomers having 11 to 12 carbon atoms is 0 to 30% by volume, the content of oligomers having 13 to 15 carbon atoms is 20 to 95% by volume and the content of oligomers having 16 to 21 carbon atoms is 5 to 50% by volume.  The paper sizing agent provides a homogeneous transparent sizing agent, which restrains the amount of the foaming and also has improved sizing effects.
